Ares Angle seat valves were selected for improving the Long Beach Wave Fountain because of their high cycle-life, durability and reliability, and compact assembly. These 2/2-way pneumatically actuated piston valves were originally designed for liquids, gases, steam and some aggressive fluids applications. The valve body and internal components are made entirely of AISI 316 SS (Ares Series) and the seals are in PTFE, therefore enabling a high chemical compatibility with almost all media used in the different production processes. The valve is also available in Brass & 316 SS (Zeus Series). The special internal conformation of the valve seat avoids excessive deformation of the PTFE seal at high temperature or pressure. The valves work well in a wide temperature range, from -14 to 358F. The stainless steel spring and the particular shape of the dual self-adjusting stem seals, ensure a perfect tightness through wear and tear of time. Available in sizes from 3/8″ to 2″, the pneumatic valve is small, but with a series of 135 jets, packs a big wave.
